Cloud computing is based on virtualization, where a single physical resource is virtualized into multiple virtual resources. Processor and network virtualization offer many advantages like saving in hardware cost, energy consumption, human effort and management of resources. In this paper we have evaluated the effect of network and processor virtualization(More)
In low-power low-rate wireless networks, IEEE 802.15.4 is a standard protocol for communication. Devices in such networks are usually battery-operated so radio-transceiver component in such networks are typically of low range but most power consuming. Proper antenna orientation, distance between nodes and channel selection are among the ways to achieve(More)
In this paper, a new transport protocol called Sensor Reliability and Congestion Control Protocol (SRCP) is proposed for Wireless Sensor Networks (WSNs) which has both the functionalities of providing end-to-end reliability as well as delaybased congestion detection and control. It uses packet sequence numbering and Selective Negative Acknowledgements(More)
Energy efficiency is an important design paradigm in Wireless Sensor Networks (WSNs) and its consumption in dynamic environment is even more critical. Duty cycling of sensor nodes is used to address the energy consumption problem. However, along with advantages, duty cycle aware networks introduce some complexities like synchronization and latency. Due to(More)
